Characters of current type Ia supernovae data based on evolving dark energy models
dark energy theory supernova type Ia - standard candles cosmological param-eters from CMBR
2010/11/11
We study characters of recent type Ia supernova (SNIa) data using evolving dark energy models with changing equation of state parameter w. We consider sudden-jump approximation of w for some chosen re...
The revival of an explosion mechanism of massive stars - the quark hadron phase transition during the early post bounce phase of core collapse supernovae
Core collapse supernovae protoneutron stars general relativity radiation hydrodynamics
2010/11/16
We explore explosions of massive stars, which are triggered via the quark hadron phase transition during the early post bounce phase of core collapse supernovae. The onset of quark matter is favored u...
Theory holds that a star born with an initial mass between about 8 and 140 times the mass of the Sun will end its life through the catastrophic gravita- tional collapse of its iron core to a neutron s...
A new multi-dimensional general relativistic neutrino hydrodynamics code for core-collapse supernovae. I. Method and code tests in spherical symmetry
general relativistic core-collapse supernovae neutrino hydrodynamics code
2010/3/19
We present a new general relativistic (GR) code for hydrodynamic supernova simulations with neutrino transport in spherical and azimuthal symmetry (1D/2D). The code is a combination of the CoCoNuT hyd...
